Answer:

Option A is correct.

The first step in solving the inequality is:

to distribute -4 to get  -8x + 4> 5-3x

Step-by-step explanation:

The distributive property says that:

a\cdot(b+c) =a\cdot b + a\cdot c

Given the inequality:

-4(2x-1)> 5-3x

Apply the distributive property we have;

-4 \cdot (2x) -4\cdot (-1)> 5-3x

Simplify:

-8x + 4> 5-3x

Therefore, the first step in solving the inequality is:

to distribute -4 to get  -8x + 4> 5-3x

Distribute –4 to get –8x + 4 > 5 – 3x.

<h3>Further explanation</h3>

The inequality –4(2x – 1) > 5 – 3x.

We will solve the problem of inequality of one variable. Here are the steps:

<u>Step-1:</u> Distribute –4 to get –8x + 4 > 5 – 3x.

–4(2x – 1) > 5 – 3x

-4(2x) + (-4)(-1) > 5 – 3x

-8x + 4 > 5 – 3x

Therefore, a correct first step in solving the inequality: Distribute –4 to get –8x + 4 > 5 – 3x.

<u>Step-2:</u> Subtract 4 from both sides of the inequality

-8x + 4 - 4 > 5 - 4 – 3x

-8x > 1 – 3x

<u>Step-3:</u> Add 3x from both sides of the inequality

-8x + 3x > 1 – 3x + 3x

-5x > 1

<u>Step-4:</u> Divide -5 from both sides of the inequality

\boxed{ \ \frac{-5x}{-5} > \frac{1}{-5} \ }

Thus, the solution is  \boxed{\boxed{ \ x < -\frac{1}{5} \ }}

- - - - - - - - - -

Notes:

  • The Distributive Property:  \boxed{ \ A(B + C) = A \cdot B + A \cdot C \ } or \boxed{ \ A(B - C) = A \cdot B - A \cdot C \ }
  • If inequality is multiplied or divided by a negative number, then the sign of the inequality changes.

Answer:

1.) slope=2

2.) slope=-3

3.) slope=\frac{1}{4}

4.) slope=-\frac{4}{5}

Step-by-step explanation:

The unit rate is also known as slope. Slope is the change in the y values over the change in the x values:

(x_{1},y_{1})\\\\(x_{2},y_{2})\\\\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=slope

However, with certain graphs, the slope can be found in a simpler manner.

  • You start at one point and move across the y-axis, then move along the x-axis until you reach another point on the same line.
  • Make sure you move on the y-axis first, then the x-axis. Record the slope as spaces moved in each \frac{y}{x}
  • When you move up, the number will be positive (\frac{+y}{x}). If you move down, the number will be negative (\frac{-y}{x}).
  • If you move to the right, the number will be positive (\frac{y}{+x}). If you move to the left, the number will be negative (\frac{y}{-x}).

What is the y-intercept of the line given by the equation y = 3x - 11?
-Dominant- [34]

Answer:

(0, - 11 )

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 11 ← is in slope- intercept form

with c = - 11 ⇒ (0, - 11 ) ← coordinates of y- intercept
